Adding two negative numbers is easy: you're just adding two "negative" arrows, so it's just like "regular" addition, but in the opposite direction. For instance, 4 + 6 = 10, and –4 – 6 = –4 + (–6) = –10.

Answer:
It's the first answer. Remember, equations like that are always y=mx+b. Y is whatever y value, m is the slope, x whatever the x value is. b is the y intercept (the y value when x equals 0). In this case, you can tell that 1/2 and 2 are the m, m is slope, so the first option should be correct.

Which is the equation of an ellipse with directrices at y = ±2 and foci at (0, 1) and (0, −1)?
(possible answers shown in image)
Answer:
[tex]\frac{x^{2} }{1} +\frac{y^{2} }{2}=1[/tex]
Step-by-step explanation:
The directrices of an ellipse are defined by
[tex]x=(+-)\frac{a}{e}[/tex]
Where [tex]a >b[/tex], and [tex]e[/tex] is the eccentricity defined by [tex]e=\frac{c}{a}[/tex]
So, in the first choice, we have the equation
[tex]\frac{x^{2} }{4}+\frac{y^{2} }{1} =1[/tex]
Where [tex]a^{2}=4[/tex] and [tex]b^{2}=1[/tex], which means [tex]a=2[/tex] and [tex]b=1[/tex].
In an ellipse, we have the relation
[tex]c^{2}=a^{2}-b^{2}[/tex]
Replacing values, we have
[tex]c^{2} =4-1=3\\c=\sqrt{3}[/tex]
So, the eccentricity is [tex]e=\frac{\sqrt{3} }{2}[/tex] and the directrices are [tex]x=(+-)\frac{2}{\sqrt{3} }[/tex], which means the first choice is not the right answer. In other words, the right answer is the second choice, because third and fourth choices don't represent an ellipse, both fractions must be positive in that case.
Therefore, the right answer is
[tex]\frac{x^{2} }{1} +\frac{y^{2} }{2}=1[/tex]
Answer:
OPTION B IS CORRECT
Step-by-step explanation:
FOR A VERTICAL ELLIPSE a IS ALWAYS LARGER THAN b AND a is always right under y-squared in the equation.

You invest $200 in a savings account. The account pays 3% interest compounded monthly. How
much money is in the account after 8 years?
Final answer:
To find out how much money will be in the account after 8 years with $200 initial investment and a 3% interest compounded monthly, use the compound interest formula A = P(1 + r/n)^(nt). The calculation results in approximately $256.67 in the account after 8 years.
Explanation:
To calculate how much money will be in the savings account after 8 years with an initial investment of $200 and a 3% interest rate compounded monthly, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (decimal).n is the number of times that interest is compounded per year.t is the time the money is invested for, in years.In this case, P = $200, r = 0.03, n = 12 (since interest is compounded monthly), and t = 8.
The formula becomes:
A = 200(1 + 0.03/12)^(12*8)
Calculating this we get:
A = 200(1 + 0.0025)^(96)
A = 200(1.0025)^96
A = 200(1.283362)
A ≈ $256.67
After 8 years, the savings account will have approximately $256.67.

Question 6:
Factor 5x4 – 20x3 + 20x2
completely.
The factors of the given expression are 5x², (x - 2), and (x - 2).
What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.
It is given that the polynomial expression 5x⁴ – 20x³ + 20x²
It is required to find its factor.
We have a polynomial expression let's denote it with f(x)
f(x) = 5x⁴ – 20x³ + 20x²
taking 5x² common
f(x) = (x²-4x +4) 5x²
from the formula (a -b)² = a² +b² -2ab
f(x) = (x -2)²*5x²
Thus, the factors of the given expression are 5x², (x - 2), and (x - 2).

Answer:
B. 12m + 6
Step-by-step explanation:
Just distribute the 3 to both 4m and 2.
Answer:

Step-by-step explanation:
Because there is a three, we must do three times both of the terms:
(3 x 4m) + (3 x 2)
When you do it, we get:
12m + 6
We cannot simplify it any further, so 12m + 6 is out final answer.

Nala is designing a piece of jewelry made of wire that has the shape shown below. It consists of two sides of a square and three-quarters of a circle. To the nearest tenth, what is the length of wire needed? Note that no wire is needed along the dashed line segment. (the curved part is three fourths the circumference)
(1) 14.1
(2) 18.4
(3) 20.1
(4) 24.8
Answer:
Option (3) is the answer.
Step-by-step explanation:
Given question is incomplete; find the complete question in the attachment.
Jewelry made by Nala is a composite figure having three fourth of a circle and two sides of a square.
Perimeter of the whole figure will give us the length of wire needed to design the jewelry.
Perimeter of three fourth of a circle P(circle) = [tex]\frac{3}{4}(2\pi r)[/tex]
Here, r = radius
P(circle) = [tex]\frac{3\pi (3)}{2}[/tex]
= 14.14 cm
Perimeter of the complete (composite) figure = 14.14 + 3 + 3
= 20.13
≈ 20.1 cm
Therefore, Option (3) is the answer.

Hope this helps!What quadrilaterals can you draw that have two sides with length 7 cm and two sides with length
4 cm?
Which of these quadrilaterals can have two sides with length 7 cm and two sides with length 4 cm?
Select all that apply.
O A. Square
B. Rectangle
C. Trapezoid
OD. Parallelogram
Final answer:
Quadrilaterals that can have two sides of length 7 cm and two of length 4 cm are a rectangle and a parallelogram; a square cannot, and a trapezoid is not certain.
Explanation:
The type of quadrilaterals that can be drawn with two sides of length 7 cm and two sides of length 4 cm are a rectangle and a parallelogram. A square cannot have sides of different lengths, so it wouldn't fit the requirement. A trapezoid could possibly have these side lengths, but only if the non-parallel sides are of different lengths, which isn't stated in the question.
The reason for choosing a rectangle is because it has four right angles and the opposite sides are equal, allowing for two sides to be 7 cm and the other two to be 4 cm. A parallelogram can also have sides of these lengths as long as the opposite sides are equal, and the angles are not restricted to 90 degrees like in a rectangle.

what is the probability that the student is
male, given that the student participates
in sports?
Answer choices:
0.379
0.42
0.524
0.58
Answer:
0.524
Step-by-step explanation:
The probability that the chosen student is a male is 0.524 .
Given,
Number of male students who participated in sports = 110
Number of female students who participated in sports = 100
Number of male students who did not participated in sports = 180
Number of female students who did not participated in sports = 210
Now,
The probability that the male students is chosen will be given by,
P(MALE) = 110/210
P(MALE) = 55/105
P(MALE) = 11/21
P(MALE) = 0.524
Thus the probability of chosing a male student who participates in the sport is 0.524 .

Identify all solutions for a triangle with A = 38 degrees b = 10, and a= 8. Round to the nearest tenth.
Answer:
A = 38°
B = 50.32°
C = 91.68°
a = 8
b = 10
c = 12.77
Step-by-step explanation:
The first thing is to find the angle B, like this:
sin B = b * sin A / a = 10 * sin (38 °) / 8
sin B = 0.77
B = arc sin (0.77)
B = 50.32 °
For angle C, it would be:
C = 180 - 38 - 50.32
C = 91.68 °
Side c, we calculate it like this:
c = a * sin C / sin A = 8 * sin (91.68 °) / sin (38 °)
c = 12.77
